Electromagnetic chucks

Electromagnetic chucks

Electromagnetic chuck for grinding generate their clamping force due to electromagnetic circuit stored in the body of the fixture. According to a development of the intended use and may comprise one or several coils which can be arranged along or transversely to the body harness. The second important component is pin board, through which electromagnetic field penetrates into the workpiece. The construction of pole plates usually consist of steel and brass blades having different widths, depending on the use (dense polarity results in a lower magnetic field of the pole plates and is suitable for clamping small and thin pieces, while the broader polarity provides a higher magnetic field of the pole board and is thus more suitable for clamping the bold and large pieces). In some cases it may be of brass The pole structure is replaced with an epoxy resin. Electromagnetic chucks are supplied with direct current, the voltage is 110 VDC. Therefore, these types require special power supplies, in addition to the power-hatted as Demagnetizer - when switched off, the electromagnet starts demagnetizer cycle, which minimizes the residual magnetism in the workpiece. Nowadays, modern resources for electromagnetic chucks have all its functions controlled by a microprocessor and, moreover, they can be degaussing program set up for a variety of specific materials (construction steel, alloy steel, tool steel, etc.). The biggest advantage compared to permanent electromagnetic chuck is therefore their ability to complete or at least partial removal of residual magnetism from the workpiece.
